The paper concerns the travel activities and more specifically the urban travel time during a day. The daily TTB has been hypothesized by Zahavi (1980) as constant amount of time. First, the cities sprawl can easily be interpreted as a consequence of the increase in available speeds. And...

Escaping unidimensional analysis limits and linear regression irrelevancy, the duration model incorporates impacts of covariates on the duration variable and permits to test the dependence of daily travel times on elapsed time. In the perspective of a discussion of Zahavi's hypothesis, the...

The paper is concerned with the travel activity and more specifically the urban travel time during a day. This individual mean travel time budget (TTB) has been hypothesised by Zahavi (1980) to be a constant amount of time close to 1 hour per day. This TTB seems to be stable between different...
